Not to mention the faster delivery times... The real benefit there has been changing the way I shop and think about shopping. I think I save massive amounts of time by almost never going to stores again. Even if the time savings is moot in the end, the psychological benefit of never having to go to stores has been wonderful. How much is that worth? I don't know, but it feels like almost zero cost given the value I get from Prime Video and Music (again, I admit that those services aren't "great").
